Hi,
Thought that some here might be interested in the new reproduction WPC Dot Matrix Controller Board which I have made and am selling through my
ebay accountThese boards have been made from the original circuit the silk screen shows what the components are in the event that something ever goes wrong and they need to be repaired. A couple of improvements have been made over the original design such as 10W resistors, larger heatsinks for the transistors and spacing the components out allowing better air flow.
